I've opted for brakes for all my rifles (specwar cans) on the premise "the brake provides a sacrificial set of baffles" but curious if anyone has any real hard information to back that statement up? It seems like it might be true on the surface but is there any scientific testing to back that up?
It's more curiosity than anything, like most folks I'm definitely in the 'once you can, you never can't' in regards to using a can, so the obnoxiousness that is the brake versus the flash hider isn't a problem. I also know that it's pretty unlikely barring a zombie uprising that has me caught inside a Lake City warehouse fighting off the undead that I'm unlikely to shoot any given can enough to 'wear it out'. But I see the phrase thrown out there quite a lot and again it seems like it would work that way but if anyone has any data to back up it would be interesting to hear. |

This reminds me that I need to be on the lookout for a brake to use for my Specwar 556 (in jail). I am not impressed with the Trifecta that comes with the can. Well, normally you should have the choice between the Trifecta or the brake. Did you not order from Silencer Shop?

I was not going to wait a month just to transfer the same can that was already in my local store. Rainier Arms. |

Quoted: TescoVee, Are those your AAC mounts? Any idea what the round count is on them?  Expect an increase in erosion with decreased barrel length. I would have a higher round count but I was running a FH until recently.

Brakes do provide a sacrificial part. However, they also concentrate the blast on a small area of the suppressor's blast baffle rather than let it diffuse outward. That makes sense. The brake is blasting that suppressor from both sides instead of expelling the gas forward. Hmm...what to do.... Edit with a further question: in terms of sbr's and long term usage....is a brake more harmful to can vs. a flash hider type device? |

Too bad you didnt see the buy one get one sale Sico was running on muzzle devices for black fri/ cyber mon. |

Cool pics. I've only just started getting into the sub 12" range and that's kind of what piqued my curiosity. My 10.5 in BO I shoot mostly subs anyway and the cartridge is designed to burn it all before it leaves the barrel so it's probably not a big issue? I am though building an 11.5" carbine gas SBR in 556 at the moment (stupid black friday sales) which will need a mount on it and before that GT comment I was going to pick up a brake but now I'm not so sure. And at some point I was going to try a shorty pistol gas build because it sounds more challenging to get it to run like clockwork and with a can it would still be shorter than a 16" without.
So.... given someone from gemtech has chimed in, is there an industry recommendation on which provides a longer lifespan on the 'typical' can, the FH or the brake when using shorter barrels? Or is it a wash and just wears in different areas? i.e. are now just concentrating the blast sideways from the brake channels and directed against the sides of the blast chamber versus what would probably be a more diffused forward blast into the first baffle? |

He doesn't state it concentrates the blast on the expansion chamber. The expansion chamber is taking the blast after it has been bounced off the brake's baffles. |
| On the Silencerco cans they say the brake vs flash hider does not matter they are not noticing a wear difference, but Silencerco typically has a blast baffle that is made out of a superior material that is heat hardened. The brake effectively shifts some wear from the first baffle to the blast chamber itself, by not only shifting the blast to the chamber (suppressor) walls, but to specific areas of the suppressor wall. For example if you are using a two chamber brake you can typically look inside the can and see were the blast is hitting the sides of the blast chamber, two oval areas on each side of the can. I'm not saying either way is better, but the baffle can be replaced by the manufacturer under warranty the suppressor body can not. |

I had YHM tell me the same thing as SiCo for the following builds: 10.5" 5.56, 10" 300BLK, 12" 6.8. Both said to choose the muzzle device I liked best.
That's why I have YHM flash hiders on every build, and swap the LT (and ULT when approved) and Sakers among all hosts. |
